Underordinary circumstances when the exhaust is forced directly to the muilier, there is considerable' back-pressure resulting in a certain loss of power by impeding the action of the motor, consequently, what are known as cut out" valves,- are frequently provided wherebytheexhaust'may be permitted to escape-directly'through the valve and into the air instead .of through the muiiier. In exhaust valves-and horns of this class, there is atendencyof the parts and ports to be come covered and clogged with carbon in the form of soot by the action of the exhaust gases,-and the primary, object of this invention is to provide aenerallyimprovedcombined Cut-0L1i',V flI1d signal horn of this class, of simple, cheap, and eiiicient construction, in which the several parts are so disposed, constructedfiand arranged asto reduce the above mentioned tendency'to'a minimum. p a

A further object of the invention is to provide avalve of this class capable of receiving the exhaust from explosive engines and distributing thesame either to the Inuflier or to another point of discharge without producing an undue accumulation ofbackpressure. This point of discharge may be directly to the atmosphere through the cutout valve, or indirectly thereto through the horn portion of the valve body above referred to.

signal horn, the horn valve being in its operative position for diverting the operating fluid or exhaust gases to the horn or whistle slot opening for sounding the horn in a well known manner. Fig.2, a side elevation of same with removable head of the valve body or casing removed. Fig. 3, a longitudinal sectional view of the same. Fig. 4, a side elevation of same, showing the horn valve shifted out of its operative position and allowing the exhaust gases or operating fluid to pass unobstructed to the mufller, a portion of its walls being broken away for clearer illustration of the parts. Fig. 5, a detail perspective view of the horn valve removed from the valve casing.

Similar numerals of reference designate like parts throughout all the figures of the drawings. v

The improved valve and horn comprises a valve body or casing 1, (preferably of cy-' lindrical form as shown) and provided with oppositely arranged and extending branches 2, and 3, to receive and contain the inlet and outlet branches 4, and 5, of the exhaust pipe, the outlet branch 5, thereof being adapted to lead to a mufiier when the exhaust is from an explosive engine.

The valve body or casing is provided at one side and intermediate the branches2,

and 3,witha cut-out port-opening 6, and at the other with a horn or Whistle slot 7. The

port opening 6, is preferably beveled as shown, and is normally closed by means of a valve-head 8, provided with beveled or flaring sides 8, the correspondingly beveled edges of the cutout opening 6. As a means for opening and closing the port opening 6, the valve -head is mounted upon and carried by an operating lever 9, mounted outside of the valve body and, in the present instance, ,pivotally secured thereto by means of a bearing-arm or-standard 1 0. The valve-head 8, is normally held in its closed position by means of a spring 11, in the present instance, secured tothe bearing-arm or standard 10. When'it is desired to discharge the exhaust gas directly into the atmosphere or to relieve any undue back-pressure resulting from the exhaust being forced directly to the muflier, the valve-head 8, is adapted to be lifted or opened by means of suitable connections or operating means connected to the free end 9, of the lever 9.

As a means for diverting the operating adapted to be seated upon body orcasing 1, by means of a rock or "exh aust pipe.

pivot shaft 11", said horn valve comprising a hub portion 11, and a supporting disk portion 12, carrying a curved, valve-head 13.

The curved valve-head 13, i's'adapted to con-- form 'to the contour of the inner periphery of the valve body or casing, and 18 of such. size that when moved to the position shown.

in Figs. 1, and 2, of the drawings, it is adapted to cover the inlet branch 4, of the One edge of the valve-head 13, is provided with a beveled or shear cut ting edge 13, adapted to clear the inner walls of thevalve body or casing from any I accumulating carbon when moved within said casing by the means hereinafter described.

' As a means for providing a passage forthe escape of the operating-fluid. to the whistle slot 7, when the valve-head is in its operative or fluid diverting position the front portion of the valve-head is preferably provided with a depressed or undercut portion 13 in its outer periphery so that a corresponding passage or recess will 'be (formed for the escape of the operating fluid to the whistle slot 7, as indicated mostele'arly in Fig. 2, of the drawings. The [bearing 'or pivot shaft 11", is mounted in'suitable' -bearing openings in an integralhead 'ldpagnd a removable head 15, of the valve bodfy'or casing 1. A lever bar 16, is adjustablypimounted in the projecting end of the piv'otg shaft 11 bymeans ofa screw 17 and the lever bar 16, may be operated b means ofa cord or cable 18, leadln to a toot-lever" or other operating mechamsrn (not shown) in the body of the vehicle. As a means for; returning the valve-head 13, to its initial position shown in Fig. 4, of the drawings, the leverbar 16, may be provided with a spring 19, suitably connected whereby the lever-bar 16 will be moved against the resistance of sai spring. As a means for limiting the movements of the lever-bar 16, and stopping the valve-head 13, in its proper positionsrwhen reciprocated, stop-lugs or pins 20, maybe formed, integral with the head 14, of the valve casing as shown.

; Having thus described my invention, what i I claim and desire to secure by "Letters Patentis,-- b 1 '1. A valve and horn, comprising-a valve body provided with inletand outletbranches and a whistle slot intermediate said branches, and a rotary valve mounted within said valve body and adapted to be carried in front of said inlet branch, said valve'being';

provided at its periphery with a recessed portion forming a passage for diverting the exhaust'gases from said inlet branch to said whistle slotv when moved in front of said.

inlet branch. v i

2. In a valve and horn, the combination with an exhaust pipe, and a valve body cpn nected thereto and provided with a whistleslot intermediate the inlet and outlet branches of said exhaust-pipe; of a rotary valve-head mounted within said valve body and adapted to be carried in front of. said inlet branch, said valve-head being provided on its periphery with a recessed portion forming a passa e for diverting the exhaust gases from said inlet branch to said whistleslot- In testimony whereof I have aflixed my signature, in presence of two witnesses.
